Apparatus for converting broadcast signal and method for using the same

An apparatus for converting a terrestrial broadcast signal into a cable broadcast signal, comprising:

• a demultiplexer unit for receiving the terrestrial broadcast signal and generating a terrestrial signaling signal based on the terrestrial broadcast signal;
• a signaling conversion unit for converting the terrestrial signaling signal into a cable signaling signal by parsing the terrestrial signaling signal;
• a cable multiplexer unit for generating the cable broadcast signal by multiplexing the cable signaling signal and a cable broadcast media signal;
• and
• a cable modulation unit for modulating the cable broadcast signal and transmitting the modulated cable broadcast signal over a cable network,
• wherein the signaling conversion unit acquires information about a position of a Service-Layer Signaling (SLS) signal by parsing a Low-Level Signaling (LLS) signal of the terrestrial signaling signal,
• wherein the signaling conversion unit acquires the SLS signal from the demultiplexer unit using the information about the position of the SLS signal, parses the acquired SLS signal, and delivers information acquired by parsing the SLS signal to the demultiplexer unit,
• wherein the demultiplexer unit generates a terrestrial broadcast media signal based on the information acquired by parsing the SLS signal, and
• wherein the apparatus further comprises a media conversion unit for converting the terrestrial broadcast media signal into the cable broadcast media signal by changing a format of the terrestrial broadcast media signal.
